Log Shipping Record Attributes

When shipping nuu:bit domain logs to a customer-defined location (like S3 bucket or SFTP server) the following attributes (fields) are included in every shipped record:

Field name

Description

Example of field value

_id

Unique ID of the record

"598a7f803edd55c777fdf81d"

host

nuu:bit's edge server which served the request

"VIE02-BP06.REVSW.NET"

@timestamp

Request completion time (in UTC time zone)

"2017-08-09T03:20:18.000Z"

unixtime

Request completion time in timestamp format

1502248818.853

domain

The domain name of served HTTP request

"www.example.com"

ipport

nuu:bit edge TCP/IP port used to serve the request

"80" for HTTP requests, "443" for HTTPS requests

response

HTTP response status code

"200"

request

The path part of the request URL (without the protocol prefix and domain name)

"/image.jpg"

s_bytes

Total number of bytes (header+body) sent from the nuu:bit edge proxy to end user

12363

s_body_bytes

The size of response's body in bytes

12014

r_bytes

Total number of bytes (header+body) received from end user to the the nuu:bit edge proxy

321

method

HTTP request method

"GET"

conn_status

The request completion status (as detected by the edge proxy)

"OK" for requests (objects) which the proxy managed to successfully sent to end user, empty string ("") for failed transmissions

KA

The number of requests handled on the same HTTP keep-alive'd connection

"1" if this is the first request served on a connection; "4" if this is the 4th served requests

FBT_mu

First Byte Time (FBT) in microseconds as measured by the edge proxy. For cache hits the timer represent the time it took to fetch the object from memory or disk cache, for cache misses the timer reports how long it took to pull the object from the origin or nuu:bit secondary cache.

Normally "0" for cache hits; a number like "123423" (in microseconds) translates to 123.423 ms.
